XeF₄ adopts which geometry?
ATetrahedral
BSquare planar
CSquare pyramidal
DSee-saw
Answer & Solution
Correct answer: B. Square planar
XeF₄ is AB₄E₂ (4 bp + 2 lp) on an octahedral frame. The two lone pairs occupy *trans* axial positions to minimise lp–lp repulsion, leaving the four F atoms in a **square planar** arrangement.
